Latest version: WinLens3D 1.1.9
[part of WinLens suite] Full optical design package with optimization.
Try the free version WinLens3D Basic.
Easy to use, but with serious capabilities - developed for the LINOS Photonics R&D department. Used by many universities for teaching optical design. Includes MTF calculations, wavefront plots, ghost analysis and interactive glass maps. Full 3D setup [handles tilts and decenters on surfaces, elements, modules and groups] and analysis capabilities - including prism wizard.
The video clips are arranged in a sequence, so that related items are together. There is a plan behind the sequence, but feel free to view them in any order.
We start with a very simple introduction to using WinLens3D. There follows a number of videos which should be of help to those teaching or learning lens design - where we describe the tools available for simple paraxial & seidel analysis and then discuss some of the graphs and what they mean. We then have some clips looking at the Tilt and Decenter features within WinLens3D - what they are and how to setup various systems using them.
We will be adding more clips on different subjects as time goes on - for example on optimisation and on some of the engineering tools within WinLens. Don’t forget that you can rate and comment on the videos!

Version history
| WinLens3D 1.1.9February 25, 2010 | - bug fix. Zemax import. corrected out of range error import zemax design with object surface NOT surf 0 AND stop at rear! |
| WinLens3D 1.1.8December 03, 2009 | - bug fix. Toric RayTrace - ray missing surface. If a ray cannot intersect with a surface [ignoring apertures], then a flag is set and the ray trace ceases. For toric raytraces, this ‘ray miss’ was properly detected, but the flag was not set, so the raytrace continued spuriously. The flag is now set appropriately. |
| WinLens3D 1.1.7October 16, 2009 | - enhancement. slider - defocus. If angular aberrations are selected, a slider controlling defocus will change the angular defocus [previously only linear defocus was altered] |
| WinLens3D 1.1.6September 18, 2009 | - bug fix. paraxial raytrace at secondary wavelengths. If the chosen field parameter is image size or image angle. paraxial raytrace was setup so that, at the secondary wavelengths, the system had the same paraxial image value as at the mid [primary] wavelength. By contrast, the real ray trace, at any wavelength always works from the same object point - this being the ‘real thing’. These were not used anywhere else, except in the distortion calcs, where it caused an obvious offset of the ‘red’ and ‘blue’ values. This has now been changed, so that the paraxial raytrace now copies the real raytrace. |
| WinLens3D 1.1.5August 20, 2009 | - object surface now shown in 3D drawing |
| WinLens3D 1.1.4July 17, 2009 | - main form no longer maximised on load & its position is remembered |
| WinLens3D 1.1.3June 19, 2009 | - bug fix: tilt data for a component was lost if re-editing existing component in its specialised editor |
| WinLens3D 1.1.2May 20, 2009 | Launch version on CD’s given away at Munich Laser show |
